Abstract

Concepts from evolutionary biology are conjoined with a Kantian‐ and Nietzschian‐based critique to demonstrate that our human concepts and perspectives are hopelessly ‘earthbound.’ Unless the caprice of evolutionary biology on some Earth‐like planet replicates the evolutionary history of Earth, we shall not recognise alien intelligence. To suggest that another planet is likely to produce a recognisable intelligence because its evolutionary history is similar to ours is simply absurd, but will seem absurd only to those with a knowledge of bio‐evolution, an understanding of our linguistic and syntactical abilities, and concepts of space, time, and causality. This conclusion may appear heavy‐handed, even pedestrian. However, a closer scrutiny reveals that it is the search for extra‐terrestrial intelligence which is naive.
